摘要：
Magnetocaloric and colossal magnetoresistance effects of the layered perovskite La1.4Sr1.6Mn2O7 compound have been studied. A broad peak of magnetic entropy change (-Delta S-M) is found above the Curie temperature (T-C=120 K), which can be associated with the existence of two-dimensional short range ferromagnetic order. Additionally, the curvilinear shape of -Delta S-M for layered perovskite is quite different from that of the Ln(1-x)A(x)MnO(3) probably arising from magnetocrystalline anisotropy. At the same time, a wide peak of colossal magnetoresitance effect near T-C is found in the layered provskite La1.4Sr1.6Mn2O7.
